List of Connecticut area codes
This is a list of area codes in Connecticut:[1]
- 203: Covering southwestern Connecticut (Fairfield County (except for Sherman); New Haven County, and the towns of Bethlehem, Woodbury, as well as a small part of Roxbury in Litchfield County); one of the original area codes enacted in 1947
- 475: Overlay of 203 (December 2009)
- 860: Northern and southeastern Connecticut (split from 203 in August 1995)
- 959: Overlay of 860 (August 2014)
In 1999, Connecticut announced that two additional codes may be implemented when needed: 475, overlaying 203; and 959, overlaying 860. In March 2009, NANPA announced area code 475 to overlay 203 in December 2009.
